The Keg Land Dual Controller features dual plugs so you can control both a cooling unit and electric heater at the same time, via the separate heat and cool plugs in the bag of the unit.  For example, get a chest freezer or refrigerator, and put a Brewer’s Edge Space Heater inside the refrigerator. Plug both the Space Heater and Refrigerator in the Heat and Cool plugs on the back of the control, and set the temperature for 55° F.  The Keg Land Controller will turn on the refrigerator when the temperature gets warmer than 55° and then turn on the Space heater if the temperature drops below 53° or so (depending on the delay you have programmed in).  Many things can be controlled:  wine cellars, fermentation areas, mash temperatures, green houses, pet enclosures,  your imagination is the limit.

 It can also be programmed to step temperature up or down over a period of time (up to 12 separate steps).  For optimum fermentation conditions using a chest freezer or refrigerator you can program the Keg King to start fermenting at one temperature, increase the temperature after a number of days and then crash chill. This is done without any intervention at all. Just program the control and forget.

You can also use this to increase the temperature of your electric mash tun so it will automatically step the temperature up and down as you please during a time period your specify.

 Distillation mode is included, which means it will only heat cycle the unit once. What this means is if you set the temperature to 175° F., it will heat until it reaches 175° and then turn off, sounding an alarm to let you know the heat has been turned off. This can be handy with electric distillation and other uses when constant monitoring is not needed.

 Other features include an adjustable differential, adjustable delay between the start of cooling and heating, or between the start of heating and cooling, cooling start delay, Centigrade and Fahrenheit modes, and adjustable high and low temperature alarms.

  Unlike the simpler Uni-Stat and Brewer’s Edge Mash Heat Control, all features are accessed through programming; see the instruction pdf below for more details.   Includes a 6’ waterproof probe cord with stainless probe tip, and a  4’ power cord.  The stainless probe fits in all the thermowells we sell, and is exactly 1/4" in outer diameter.  Works from -49°F up to 248°F, and features a 10 amp cooling relay, and 13 amp separate heating relay so it can handle the load of any 110 volt electric heater.

A common question we get is how to set the Dual Controller to Fahrenheit. To do this, follow the steps below:

 1. First hold the lower right set key down for about 6 seconds until it flashes E3.

 2. Then press the lower right set key 9 times to get to C1

 3. Then press the upper left arrow button once to change the display to 01

 4. You will see 01 displaying for a few seconds and then it will return to display the temperature in Fahrenheit.

KNOWN BUG: The software for this unit has a known bug. When the unit is set to Fahrenheit, it works in Fahrenheit but a small c is displayed, like it is Centigrade mode, on the upper right part of the display. However, the setting is Fahrenheit, and the unit will stay in Fahrenheit mode until unplugged.

Keg Land Dual Plug Control
My review is mixed.  This product worked great for 3 years and then it stopped heating the water. I opened the component to find the wiring to the “heat” plugged fried and melted. I had to order a replacement. 

My use of the component at the time was normal and nothing out of the ordinary so I was puzzled why it fizzled.

Keg Land Dual Controller
The controller gets 3.5 stars. It Is a wee bit cumbersome to program and to adjust on the fly. It does hold a decent temp. My issue with it is changing the set time and temperature can be tedious. You will need to keep a flow chart or spreadsheet if you want to do some long term temp changes. 

Williams Brewing gets 5 stars. My first temp controller did not work out of the box. I sent an email to their customer service department during the Christmas/ New Year holiday season and I received a response back almost immediately. The response was perfect too. “We apologize for that. The replacement is on the way.”  

Williams has earned my respect and my business.

This is excellent
I bought this to control a fermentation fridge. It is easy to set up and program. Best if all, it holds the fridge temp spot on. Great produce. Excellent service.

Finally a thermostat plug that works as basic as an old school analog dial, or as complex as you could dream up for the price.

Will this work with only a mini fridge plugged into the cooling plug to keep a constant 33° temp?
Providing the Mini Fridge has a robust enough compressor to get down to 33 degrees, it may work. Keep in mind it will not be a constant 33 degrees, as every thermostat has a differential of 3 degrees or so to save the compressor from constant stop and starts. So if you set it at 33, assuming the compressor is powerful enough to get to 33, it will then turn off and rise to 36 degrees before switching on again.

Will this control work a 110 volt, 2 position, motorized ball vale?
We have not tested this application, so we cannot say for sure.

Love the product. One question I have is whether or not I can keep the unit set as Fahrenheit even after unplugging it from power? It seems to reset back to Celsius when I plug it back in on a new brew day. Thanks.
Yes, it does reset to celsius when you unplug it.
